SASH-FASTEN ER.

SPECIFICATION forming part Of Letters Patent NO. 281,714, dated July24, 1883.

Application filed August 16, 1881. (No model.) I

IO specification.

The object of my invention is to provide means of regulating the opening of either or both sashes of a window.

In order that the specification may be better understood, I have accompanied it with drawings representing the different parts and their application.

Figure 1 represents a perspective View of a window with my safety-chain attached to the sash. Fig. 2 represents a front view of the chain removed from the window-sash. Figs. 3 and 4 represent side and top views of the threaded plate, and Fig. 5 represents a perspective View of the slotted plate.

The chain, as represented in Fig. 2, is composed of a threaded bolt, F, bars E and 0, (being together about eight inches long,) and a regular link-chain, A, about eight inches long from the point a, where it is connected to bar O, to the guardD on the other end of said chain. A plate of metal, G, as shown in Figs. 3 and 4, is made with a projection, said projection being at right angles to the plate. A

screw-threaded hole is made in this projection for the purpose of receiving bolt F. Screwholes 0 c are made in the plate for screwing the plate upon the upper window-sash; andv these holes are bored into the plateclose up to the projection, so that when theplate is fastened into place and the bolt F is screwed tion, e, the slot (Z of this projection being made just wide enough to permit the bars 0 and E to pass through it. This projection has also a longitudinal opening, f, through it, and this opening is for the purpose of passing the chain The plate I is to be attached, as shown in Fig. 1, about through.

eight inches above the top line of the lower sash, (I name eight inches, believing that to be about the correct limit for the object, which is protection from burglars, but this can of course be altered, if advisable,) close to the line of travel of said sash. The piece is placed so that the slit runs horizontally, and face 13 is turned toward the sash. There are three or more screwholes, 9 g g, the one being in front of an enlagement of the slit, and so placed simply for strength and facilitating the covering of the screw-head by the chain which is to run lower part of the upper sash, as shown at K, Fig. 1, the side H being toward the glass and close enough to it so that when bolt F of the chain is introduced this upper sash can freely pass the lower sash. The screw-heads c c in Fig. 4 are covered, or partially so, when bolt F of the chain is introduced. Plates G and I being in position and the window closed, the modus operand i is to introduce bar 0 through the longitudinal opening f, drawing the chain as far as guard D through the opening. Then bolt F is introduced in the screw-threaded hole in the plate G. It is now clear that the upper sash can now only be lowered eight inches, as the chain is in all sixteen inches, and one end is held eight inches above the line of meeting of the sashes, the lower sash being also prevented from being opened more than eight inches by the chain through plate I.

From its construction, the chain cannot be drawn down between the sashes, as even when the sashes are slightly separated the link part only reaches to about the meeting-line, and bar E, sliding through 0, lies horizontally without falling downward.

\Vhen this device is used in connection with my patented elongated-handle shutterbolt, which can only be drawn when the'window is entirely opened, the length of chain can be made to suit the size of the window, the object now being only to prevent the sash from being raised to its highest point, and plate I can be placed at a point within a few inches to the highest point that can be reached by the top line of the lower sash.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, substantially as before The plate G is to be attached to the set forth, of the two sliding sashes of a window, and an inside safety-chain, one end of which is detachably connected to the lower rail of the upper sash, while its other end is attached to the window-frame above the lower sash, and is removable therefrom only after first detaching the remote end, whereby the chain will stop the movement of either sash beyond a certain limit, and the detachable end of the chain will enter between the two sashes, and thus become inaccessible whenever either sash is moved.

2. The combination, substantially as before set forth, of the two sliding sashes of a window, a chain composed of partssuch as D A G Eand detachably secured at one end to the lower rail of the upper sash, and a staplesuch as l fastened to the window-frame above the lower sash, for holding the other end of said chain. 20

y 3. The combination, substantially as before set forth, of the two sliding sashes of a window, a chain composed of parts-sueh as D A C E F-a plate such as Gsecured to the lower rail of the upper sash, for holding one end of 25 said chain, and a staplesuch as I-fastened to the window-frame above the lower sash, for holding the other end of said chain.

Witness my hand this 15th day of August, A. D. 1881.
